UNITED STATES PATENT PETER SPOHN VAN WAGNER, OF STONEY GREEK, TOYVNSHIPOF SALT- FLEET, CANADA, ASSIGNOR TO HIMSELF AND ALBERT E. CARPENTER,

OF SAME PLACE.

IMPROVEMENT IN ADJUSTABLE TRACE-FASTENING.

Specification forming part of Letters Patent No. 96,852, dated November16, 1869.

To all whom it may concern:

Be it known that I, PETER SPOHN VAN WAGNER, of Stoney Creek, township ofSaltfleet, county of Wentworth, Province of Ontario, Dominion of Canada,have invented a new and improved Adjustable Trace-Fastening; and I dohereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the-art to makeand use the same, reference being had to the accompanying drawings,forming part of this specification.

The presentinvention relates to an improvement in adjustabletrace-fasteners, and consists in the employment of a olute spring, incombination with a T or ornamental arrow-head, and the whiffletree tipor socket, whereby a stiff spring occupying but little space isproduced, to permit the tip to be more firmly secured upon thewhiffletree.

I am aware that spiral springs have been used in this connection, but inorder to produce the requisite strength, it is necessary that suchsprings be made very long, and they therefore occupy so much of thehollow tip as to prevent the latter from being firmly secured upon thewhiffietree.

Figure 1 represents a section of my device.

Figure 2 is a plan of the same.

Similar letters of reference indicate corresponding parts.

In this case, A represents a metal socket for the end of thewhiffletree, on one end of which socket the hook proper, B, is cast, thesaid hook flaring, as shown in the accompanying drawing, and has agroove, 0, on its top, and also a groove, D, on the top sides of thehook proper, in which the T or ornamental arrowhead E will rest whenlocked, the spring F serving to hold the saidT or arrow-head firm in itsplace.

In fig. 1, the trace G is shown as having been just slipped over thewhifi'letree-fastening, and in order to lock the same, the T orornamental arrow-head E is turned crosswise to the button-hole in thetrace, as shown in fig. 2.

The spring F is secured in its place by the washer H, which is preventedfrom slipping off the stem of the arrow-head either by means offlattening out the end of the said stem, or by means of a pin passingthrough the said stem, as may be deemed best in practice.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

The trace-fastener herein described,consisting of the grooved socket A,arrow-head E, and spiral spring F, so constructed that the arrow -headhas only sufiicient longitudinal movement to allow it to be turned roundin the socket, substantially as specified.

The above specification of my invention signed by me, this 13th day ofMarch, 1869.

P. S. VAN WAGNER.
